Dub

Dub is a form of music which evolved out of reggae in the late 1960s, even if it not "sounded" dub until a few years into the 1970s. The dub sound consists predominantly of instrumental remixes of existing recordings and is achieved by significantly manipulating and reshaping the recordings, usually by removing the vocals from an existing music piece, emphasizing the drum and bass frequencies or 'riddim', adding extensive echo and reverb effects, and dubbing occasional snippets of lyrics from the original version.
